Badge Number Auction — one retired member number a day, highest bid wins

Site news · 2026-08-25

Your XCT member number is the badge you wear everywhere — profile, feed cards, leaderboards, member lists. New members always take the next number up, so a low one has been out of reach since the day it was issued. From today there is exactly one way to get one: win it at the Badge Number Auction .

Where the numbers come from

When a member wipes their account, or an old one is removed, their number goes back into a pool instead of being reissued. There are 64 retired numbers in it right now — some from the founding gold tier — and every future wipe adds another.

One number a day, 24 hours

At 00:00 UTC a number is drawn at random and goes on the block until the next midnight, with a live countdown on the auction page and at the top of the community feed. Tomorrow's number is always shown in advance so you can plan your Core. The first one is up now: #1219 , closing tonight at 00:00 UTC.

How bidding works

🔨 Open ascending bids in XCT Core , like eBay — opening bid 50, raise by 10 or more, and you can raise your own bid any time.

🔒 You can only bid what your balance covers, and nothing is taken until you win : your Core stays put while the auction runs. When it closes the highest bidder is charged their bid; if they have spent it elsewhere in the meantime, the next-highest wins instead.

🔄 Winning swaps your badge number. The number you win replaces your current member number everywhere on the site, and your old number drops back into the pool for a future auction. No number yet? The won number becomes yours.

Earning Core
